A.Y. McDonald Pumptec-Plus Pump Protection for 4 in Single-Phase Submersible Motors

Pumptec-Plus is a solid-state pump protection system for 1/2 to 5 HP single-phase submersible motors. It measures the actual motor power in watts, not amps or power factor, and compares it with a snapshot taken while the system runs normally. If the power draw moves more than 25% either side of that snapshot, or the line voltage leaves its range, it opens its contactor and stops the motor. Run and fault lights on the cover make diagnosis quick.

• Snapshot calibration — one button press records the normal load; the memory holds it for 10 years, even without power.
• Over and underload protection — trips at 125% and 75% of the snapshot load.
• Over and under voltage protection — trips beyond ±10% (207V / 253V) and retries every 2 minutes.
• Rapid cycle detection — 4 or more starts per minute.
• Adjustable automatic restart timer — manual reset, or 1 minute to 4 hours 16 minutes after a dry-well trip.
• 5 hp contactor, heavy-duty terminal blocks and transient surge protection.

This is Baker part 6617-143, supplied by A.Y. McDonald under the Baker number. Franklin Electric sells the same unit as order number 5800060100 (230V, 60 Hz). The 220V, 50 Hz version, 5800060502, is a different unit and is not this listing.

1. Disconnect power at the main panel. Remove the cover screw and slide the cover up.
2. Set the automatic restart timer switch (table above).
3. Mount the unit where it is convenient to wire, out of direct sunlight, rain and snow.
4. Connect the 230V supply and the motor using the 2-wire, 3-wire or 3-wire deluxe control box diagram (photo gallery). Pumptec-Plus can be wired before or after the pressure switch, float switch or other control.
5. Replace the cover and apply power. The unit will trip on overload (flashing yellow) when the pump tries to run — this is the reminder that it needs calibrating. Some 1/2 HP motors flash green instead.
6. Calibrate: hold the reset button about 10 seconds until the green, yellow and red lights blink in turn, and release; the motor starts. Within 3 minutes, confirm the system is pumping normally at maximum flow, then press and release reset once. All lights go off, and after 2 to 3 seconds the green light flashes: calibration is done.
